Archimedes' screw inspires researchers to devise a novel particle-trapping laser beam

An active field of research, laser optical trapping works to control the movement and position of particles of different sizes and shapes. The ability to move small particles in a precise and controlled manner is important to both basic and applied science. For example, the ability to control the movement of single atoms can be used to realize quantum computing, and the research also contributes to the study of biological specimens and pollutants.

A new way to measure the light-warping properties of hyperbolic metamaterials

Manipulating light in a variety of ways—shrinking its wavelength and allowing it to travel freely in one direction while stopping it cold in another—hyperbolic metamaterials have wide application in optical communications and as nanoparticle sensors. But some of the same optical properties that make these metamaterials so appealing make them frustratingly difficult to evaluate.

Biological light sensor filmed in action

Using X-ray laser technology, a team led by researchers of the Paul Scherrer Institute PSI has recorded one of the fastest processes in biology. In doing so, they produced a molecular movie that reveals how the light sensor retinal is activated in a protein molecule. Such reactions occur in numerous organisms that use the information or energy content of light – they enable certain bacteria to produce energy through photosynthesis, initiate the process of vision in humans and animals, and regulate adaptations to the circadian rhythm. The movie shows for the first time how a protein efficiently controls the reaction of the embedded light sensor. The images, now published in the journal Science, were captured at the free-electron X-ray laser LCLS at Stanford University in California. Further investigations are planned at SwissFEL, the new free-electron X-ray laser at PSI. Besides the scientists from Switzerland, researchers from Japan, the USA, Germany, Israel, and Sweden took part in this study.

Researchers report micro-CT scan of a mouse embryo at unprecedented resolution

One of the most vital research paths in genetics is the relationship between genes and embryonic growth. Noninvasive, whole-body 3-D imaging of embryos is highly important for establishing these relationships in order to determine the impact of specific genes on development. Mice are a widespread research model in genetics, but capturing 3-D imagery of mouse fetal development requires higher resolution and higher throughput than conventional micro computed tomography (micro-CT) can provide.

Multiple lasers could be replaced by a single microcomb

Every time we send an e-mail, a tweet, or stream a video, we rely on laser light to transfer digital information over a complex network of optical fibers. Dozens of high-performance lasers are needed to fill up the bandwidth and to squeeze in an increasing amount of digital data. Researchers have now shown that all these lasers can be replaced by a single device called a microcomb.

Transparent, conductive films promising for developing flexible screens

Researchers have demonstrated large-scale fabrication of a new type of transparent conductive electrode film based on nanopatterned silver. Smartphone touch screens and flat panel televisions use transparent electrodes to detect touch and to quickly switch the color of each pixel. Because silver is less brittle and more chemically resistant than materials currently used to make these electrodes, the new films could offer a high-performance and long-lasting option for use with flexible screens and electronics. The silver-based films could also enable flexible solar cells for installation on windows, roofs and even personal devices.

Cheaper and more efficient photonic devices, such as lasers, optical fibers, and other light sources may be possible with confined light that is unaffected by imperfections in the material that confines it, according to new research. A team of physicists from Penn State, the University of Pittsburgh, and the University of Illinois have demonstrated in a proof-of-concept experiment that they can contain light in such a way that makes it highly insensitive to defects that might be present in a material. The results of the research appear online on June 4, 2018 in the journal Nature Photonics.

Novel power meter opens the door for in-situ, real-time monitoring of high-power lasers

High-power lasers are now widely used in additive manufacturing and laser welding systems to precisely cut and weld metal, making all kinds of metal parts for medical devices, aerospace applications, automotive industries, and more. With the rise in industrial use of high-power laser processing, manufacturers increasingly seek high-accuracy, point-of-use laser power meters that can quickly report laser powers at any time in the manufacturing process—a vital aspect to controlling product quality. Traditional laser power meters, however, are often bulky in size and slow in response time. Power measurements can also only be taken separately, interrupting the manufacturing process.

Antiferromagnetic materials allow for processing at terahertz speeds

In high-speed fiber optics, it is often the case that either the bandwidth of the transmission media cannot keep up with the data flow or the data simply cannot be processed fast enough. Then the picture judders or the resolution is temporarily scaled down, and television viewers have to make do with lower resolution images. Soon, such low bandwidth could be a thing of the past. Researchers at the Czech Academy of Sciences, together with their colleagues at Mainz University, have discovered a way to dramatically increase data processing rates by around 100 times up to terahertz speeds.
